TBTVECATT

Description

Reports status and differences between two attribute table data from input file and reference file.

Parameter descriptions

FILI

The name of the input vector file to compare with the reference file FILI_REF.

DBVS

Specifies the input vector segments which will be tested. If the value is empty; all vector segment number will be default value.

FILI_REF

The reference file against which input file is compared.

DBVS_REF

Specifies the vector segments of reference file. If the value is empty; all vector segments will be default value.

FLDNME

Specifies Field name list that comparison will be applied. Field name should exist in input and reference vector layer. And Fields should have same data type. If the value is empty; all fields will be used as default value.

TOLERANCE

Tolerance values will be used to compare with reference data.

FILO

Specify the name of file in which the results of test will be write to. The output file is always PIX (PCIDSK) format.

Details

This function uses the tolerance value to validate data in two vector attribute tables which from input file and reference file. Output result file will include two vector segments.

First is data status vector segment. Each attribute field value present data class of status comparing input data and reference data with tolerance.

Second is data different vector segment. It will show the different between two attribute table where error happen.

Data will be classified as:

The input file and reference file must be formats supported by GDB and must have same georeference.

The each field in input field list must exist in vector segment attribute table of both input and reference files. And corresponding field mush have same data type.

If input field name list is empty; two vector segment attribute table of input and reference file must have same field list.

Example

Measure two vector segment attribute data with a tolerance value.

from pci.tbtvecatt import tbtvecatt

fili      =  'testdata.pix'
dbvs      = []
fili_ref  =  'reference.pix'
dbvs_ref  = []
fldnme    = ''
tolerance = '10'
filo      = 'output.pix'

tbtvecatt(fili, dbvs, fili_ref, dbvs_ref, fldnme, tolerance, filo)
